The BLT SMS-400 Super e-Motion Server is a 4 channel Hard Disk based Digital Recorder, with simultaneous recording and playback capability.
It combines High Speed / Super Slow Motion Camera native interface (i.e. LDK-23 HS or BVP-9500 WS), advanced disk technology with a VTR style of control and user friendly operation together with BLT RUS remote unit.
The four channels are used as three video inputs to handle the High Speed / Super Slow Motion Camera signals (3 times faster: PAL 150 fields per second, NTSC 180) and one as simultaneous playback output channel. The recording mode can be set in loop-mode for endless recording, while Clip marking with write protection allows to save the relevant recorded segments (application: High Lights).
If not connected to a High Speed / Super Slow Motion Camera, the BLT SMS-400 is used as three simultaneous channel video recorder for multi-camera application, with playback capability while recording. Digital SDI or Analog Composite video formats are accepted for easy interface and channel by channel selectable, while output video is available as SDI, CVBS and Y,R-y,B-y Analog Component format.
The BLT SMS-400 adopts internal 4:2:2, processing with M-JPEG compression (like I-frame only MPEG scheme) with data rate up-to 50 Mbit/Sec per channel. The compression CODEC is used in Constant Quality mode, that is VBR (variable bit rate), for a better and efficient use of disk space. BLT SMS-400 uses 6 SCSI Hard Disk Drives in parallel, with a BLT proprietary array and operating system. The recording time storage, depending by HDD installed, is up to 7 hours per channel in multi-camera application.
The Video output is available in digital and analog format, with a dedicated monitor-output for superimposed on-screen information (Time Code, status and other). Stand alone operation or Gen. Lock through Black-Burst or CVBS.
Furthermore, 6 mono Analog Audio inputs and outputs are included, together with Time Code LTC process (with XLR input and output).
The BLT SMS-400 Digital Recorder is housed in a 19" rack chassis, 5 U high and 48cm long, which include 6 SCSI 3"1/2 HDDs, fitted inside (either Full size 1.6" or SLIM 1"), with capacity of 36GB or 72GB available at present; provision is made for larger HDDs capacity when they will come available.
The BLT SMS-400 Digital Recorder is provided with one RS-422 serial port for remote control, as VTR style, using the BVW-75 protocol, with BLT extended commands for disk based operation.
The BLT SMS-400 is able to handle: up to 255 Clips mark (per channel), real time Clip protection, Sequence creation and edit, Recording loop, VTR control (Slow, FF, REW, Jog/Shuttle...), instant CUE-UP to any disk frame with CTL or Time Code reference, disk browse, still store....
The BLT SMS-400 is ready to be used with BLT RUS remote unit to obtain an user friendly system for live sport application. Furthermore, the RUS is able to control up to 4 devices, so even a 4 Super Slow Motion / High Speed multi-camera system (i.e. LDK-23 HS or BVP-9500 WS) can be handled by single operator.
